摘要:
The present invention provides medicinally active extracts and fractions, and a method for preparing the same by extracting and fractioning constituents from the tissue of plant components of Ganoderma lucidum. These active extracts and fractions are useful for inhibiting tumor growth, modulating immune response, and increasing hematopoietic activity.

The present invention provides a ketoaldonic acid such as an octulosonic or nonulosonic acid having a formed stereogenic center of R configuration, as well as methods of synthesizing the same.
摘要:
Inhibitors of E-, P- and L-selectin binding are synthesized by an aldol addition reaction between a glycoside aldehyde precursor and dihydroxyacetone phosphate or a derivative thereof. The addition reaction is catalyzed by aldolase. The inhibitors exhibit an activity comparable to sialyl Lewis X with respect to the E-selectin binding assay and high activities in the P- and L-selectin binding assays. The inhibitors are employable for blocking neutrophil inflamatory conditions.
摘要:
Sialyl Lewis X mimetics incorporating fucopeptides are synthesized and shown to mimic the configuration and essential functional groups of sialyl Lewis X in space. The fucopeptides exhibit substantially the same biological activity as sialyl Lewis X in the E-selectin binding assay and can be employed for blocking neutrophil inflamatory conditions.
摘要:
Methods for metabolic oligosaccharide engineering that incorporates derivatized alkyne-bearing sugar analogs as “tags” into cellular glycoconjugates are disclosed. Alkynyl derivatized Fuc and alkynyl derivatized ManNAc sugars are incorporated into cellular glycoconjugates. Chemical probes comprising an azide group and a visual or fluorogenic probe and used to label alkyne-derivatized sugar-tagged glycoconjugates are disclosed. Chemical probes bind covalently to the alkynyl group by Cu(I)-catalyzed [3+2] azide-alkyne cycloaddition and are visualized at the cell surface, intracellularly, or in a cellular extract. The labeled glycoconjugate is capable of detection by flow cytometry, SDS-PAGE, Western blot, ELISA, confocal microscopy, and mass spectrometry.
